Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm GFX 100 II and the Leica S1 Pro? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison
The physical size and weight of the Fujifilm GFX 100 II and the Leica S1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica S1 is considerably larger (308 percent) than the Fujifilm GFX 100 II. Moreover, the S1 is substantially heavier (143 percent) than the GFX 100 II. It is worth mentioning in this context that the GFX 100 II is splash and dust resistant, while the S1 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The power pack in the GFX 100 II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GFX 100 II was launched at a markedly lower price (by 65 percent) than the S1, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a medium format sensor, but their sensors differ slightly in size. The sensor area in the S1 is 10 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 0.79 (GFX 100 II) and 0.85. The sensor in the GFX 100 II has a native 4:3 aspect ratio, while the one in the S1 offers a 1:1 aspect.

With 101.8MP, the GFX 100 II offers a higher resolution than the S1 (26.4MP), but the GFX 100 II has smaller individual pixels (pixel pitch of 3.76μm versus 7.01μm for the S1). However, the GFX 100 II is a much more recent model (by 27 years) than the S1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Fujifilm GFX 100 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100 II for good quality output (200 dots per inch) amounts to 58.2 x 43.7 inches or 147.9 x 110.9 cm, for very good quality (250 dpi) 46.6 x 34.9 inches or 118.3 x 88.8 cm, and for excellent quality (300 dpi) 38.8 x 29.1 inches or 98.6 x 74 cm. The corresponding values for the Leica S1 are 25.7 x 25.7 inches or 65.3 x 65.3 cm for good quality, 20.6 x 20.6 inches or 52.2 x 52.2 cm for very good quality, and 17.1 x 17.1 inches or 43.5 x 43.5 cm for excellent quality prints.
The GFX 100 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the S1, the GFX 100 II has the capacity to capture high quality composite images (YESMP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Fujifilm GFX 100 II has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The corresponding ISO settings for the Leica S1 Pro are ISO 50 to ISO 1600 (no boost).
In terms of underlying technology, the GFX 100 II is build around a BSI-CMOS sensor, while the S1 uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GFX 100 II indeed provides movie recording capabilities, while the S1 does not. The highest resolution format that the GFX 100 II can use is 8K/30p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GFX 100 II has an electronic viewfinder (9440k dots), while the S1 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image.

One feature that is present on the GFX 100 II, but is missing on the S1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GFX 100 II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Fujifilm GFX 100 II has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The GFX 100 II writes its imaging data to CFexpress (type B) or SDXC cards, while the S1 uses external storage.
Connectivity comparison
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process.

It is notable that the GFX 100 II has a hotshoe, while the S1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Fujifilm GFX 100 II (unlike the S1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The GFX 100 II is a recent model that features in the current product line-up of Fujifilm. In contrast, the S1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the S1 was succeeded by the Leica S2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Leica websites.
Review summary
So how do things add up? Which of the two cameras – the Fujifilm GFX 100 II or the Leica S1 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Fujifilm GFX 100 II:
- More detail: Offers more megapixels (101.8 vs 26.4MP) with a 100% higher linear resolution.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Broader imaging potential: Can record not only still images but also 8K/30p movies.

- More framing info: Has an electronic viewfinder that displays shooting data.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Rear screen: Has a backside LCD (3.2") for image review and settings control.
- More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (8 vs 0.01 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (152x117mm vs 339x214mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 1470g or 59 percent) and hence easier to carry around.
- Easier travel charging: Can be conveniently charged via its USB port.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.

If the count of individual advantages (bullet points above) is taken as a guide, the GFX 100 II is the clear winner of the match-up (23 : 3 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Fujifilm GFX 100 II and the Leica S1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GFX 100 II or the S1. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
Expert reviews
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
